Servlet API中的请求方法常量在哪里？ [英] Where are the request method constants in the Servlet API?

问题描述

我想写

if (POST.equals(req.getMethod()))

而不是

if ("POST".equals(req.getMethod()))

但我找不到常量定义在Servlet API中（仅查看HttpServletRequest，我期望它们在哪里）。

but I cannot find the constant definitions in the Servlet API (only looked in HttpServletRequest, where I expected them to be).

它们在哪里（我使用了大量的库，所以如果其他人定义它们，这也可以工作）？

Where are they (I am using lots of libraries, so if someone else defines them, that would also work)?

推荐答案

Java EE 6似乎将HTTP方法名称作为常量添加到javax.ws中.rs.HttpMethod注释界面。根据您的设置，它们可能对您有用。

It appears that Java EE 6 added the HTTP method names as constants to the javax.ws.rs.HttpMethod annotation interface. Depending on your setup, they may be available to you.
